What Would Happen To Chess If Castling Was Not Allowed?

Has anyone seriously considered this? I understand that there is some push in the community to have more decisive games. One way we are already doing this is using shorter time controls, leaving more room for mistakes. I believe that removing castling rules from chess would serve this purpose as well, among other things.

Openings would of course have to adapt to the new situation. Moving your e&d pawns to occupy the center is more dangrous when your king is stuck in the middle of the board. Yet contol of the center is something you are definitely going to need to be able to defend your uncastled king in the long run. This conflicting pressure would, I believe, encourage early attacks and tactical play leading to sharp positions. The alternative would naturally be to castle manually, but that is going to cost several moves that you may not be able to afford.

Removing castling would also simplify the rules of the chess, instead of complicating them more, like chess960, for example. Complexity of the rules is one obstacle preventing chess from attracting new players and a bigger audience.

Most of a players skill in traditional chess is easily transferable to the new game, I think. Any good player is already quite cabable of attacking an uncastled king and will surely be able to take advantage of the new situation
